Introduction to relay controlled lighting systems Today, there is a practical and viable alternative to the traditional way of controlling domestic and commercial lighting.
Economy and flexibility Achieving the control of lighting where there is more than one control switch, particularly where they are located some distance from one another, has always been complicated and costly. A second control switch requires 3 additional wires, whilst every intermediate switching location requires no less than 4 wires. In such cases, utilising an impulse (or step) relay has many advantages; designing the system is simpler – it is more easily expanded – installation costs are noticeably reduced. Simplicity Using 2-wire pushbuttons to control the coil of a centrally located impulse relay, which in turn controls the lights, greatly simplifies the wiring normally associated with one-way, two-way and intermediate switches. The 2-wire coil “command circuit” is easily extended to as many lighting control locations as needed, and can use smaller and neater conductors (0.5 mm2 - CEI 64-8), since they need only to carry the load of the relay coil (typically 20÷600 mA). The power circuit to the lights should of course be of sufficient capacity, but instead of following the usual 2
route of a traditional system to all the switches, it needs to run only to the impulse relay and then to the lights.
Safety Where necessary, and particularly for safety reasons, a transformer can be used to power the command circuit at a voltage lower than the supply voltage - impulse relay coils being available in several AC or DC voltages. No other component offers this enhanced safety through separating the command from the power circuit, nor the savings derived from added versatility and simplification of the system. Versatility In addition to the technical advantages already described, a number of versatile mounting modes for the relay are possible; ranging from a normal junction box, screw fixing, and 35 mm rail (EN 60715) mounting systems.
Introduction to relay controlled lighting systems Conforming to International Standards In Europe, EU Directive 46/90 and successive amendments state that, as well as using recognised technicians to carryout the installation, the materials and components used in the system should adhere to International and National standards. It is particularly important that this can be verified with Declarations of Conformity citing the appropriate standards, and certification documents from the appropriate National certification organisation. FINDER impulse relays are designed and constructed in compliance to CEI regulations and, depending on type, have been officially certified by the appropriate standards authorities with respect to performance and quality, being subject to both Type Testing and ongoing periodic QC testing. (Refer to page 13 of this Guide)
APPROPRIATE STANDARDS EN 61810-1: Electromechanical Elementary Relays – Part 1: General and safety requirements EN 60669-1: Switches for household and similar fixed electrical installations. General requirements 64 - 8: Electrical Systems.
Noise level FINDER is engaged in continual research into the reduction of the acoustic noise generated by the mechanical action of operating the contacts. Improved with respect to earlier versions of impulse relay, the current 20, 26 Series and 27 series create no more noise than a normal switch (about 20 dB), whilst the SILENT IMPULSE RELAY “13.81” and “13.91” generates no noise noticeable above the general background noise where it is installed.

The Switching Function code The Switching Function fundamentally defines the particular sequence in which the step relay contacts open and close, and the number of “steps” before this sequence repeats itself. The digit in the fourth position of the Finder part number denotes the Switching Function.

Switching function code The 1 pole 2 step switching function xx.x1 will allow the On/Off control of a single lighting zone. The 2 pole types allow the independent control of 2 lighting zones. The specific lighting sequence will depend on the specific Switching Function code chosen. Note: • Not all Finder Step relays are available with all the possible alternative Switching functions. • The Switching function code generally has the same meaning for all Finder step relays, although there are a few minor anomalies – so in practice refer carefully to the data sheet for the specific relay. For example: The Switching Function code “6” (2 pole, 3-step sequence) can be implemented with relay types 20.26 – 26.06 – 27.06, but the latter has coil and contact circuits that are common to each other.

Comparing both systems, even for the simplest uses, the relay system offers advantages. Only two wires are required for the “command circuit”, and they can be of a smaller cross section (0.5 mm). Whereas, in a traditional system the conductors have to be

sized to take the load current and are far more numerous. From an economic viewpoint, not only are there savings in material costs, but also less time is taken by the electrician to install the relay system. This system is also much easier to modify or extend. 5

It is good practice to try to achieve a correct installation where the light emitted from the lamp(s) does not influence the light level seen by the sensor, although the “light feedback compensation” principle will help when this is not fully achievable. In this case it should be appreciated that the “light feedback compensation” principle may delay slightly the time of Switch Off - beyond the ideal. 2. The compensation principle is not effective where the combined effect of the ambient light and the controlled lighting exceeds 120 lux. 3. The 10.32 and 10.41 types are compatible with gas discharge lamps that attain full output within 10 minutes, since the electronic circuit monitors lamps' light output over a 10 minutes period to achieve a true assessment of its contribution to the overall lighting level.

15 Series - Electronic step relay and Dimmer Operating mode without memory: at switch-off, the light level is not memorized. Long control pulse: The light level is progressively raised or lowered in linear way. The lowest value depend on the “minimum dimming level” regulator setting. Short control pulse: Alternately switches between On and Off between the maximum light level and the off state. Operating mode with memory: the previous light level is memorized. Long control pulse: The light level is progressively raised or lowered in linear way. The lowest value dependent on the “minimum dimming level” regulator setting. Short control pulse: Alternately switches between On and Off. When switching On, the light level assumes the value set during the previous On state. Type of load

With memory (M) Without memory (M) • Incandescent lamps • 230 V halogen lamps • 12/24 V halogen lamps with electronic transformer/ballast
It is suggested to set the “minimum dimming level” at the lowest value, so that the complete dimming range is available. But if it is necessary to avoid too low a level of illumination, a higher value can be set.
• Dimmable compact fluorescent lamps (CFL) • Dimmable LED lamps
It is suggested to initially set the “minimum dimming level” at an intermediate value and then if necessary, readjust for a level found to be compatible with the lamp being used.
• 12/24 V halogen lamps with toroidal or E-core electromagnetic transformer
It is suggested to set the “minimum dimming level” at the lowest value, so that the complete dimming range is available. But if it is necessary to avoid too low a level of illumination, a higher value can be set.

Functions
134
(MI) Outputs alternate on successive applications of supply voltage • Application of the supply voltage to A1-A2 forces just one output contact to close, but the contact that closes will alternate between 11-14 and 21-24 on each successive application of the supply – ensuring even wear across both motors. • The other output contact can be forced closed by the closure of either S1 or S2 - but to limit high current surges the other motor cannot start within T seconds of the first motor.
Type 72.42 - Monitoring relays (ME) Outputs alternate according to control signal • The supply voltage is permanently applied to A1-A2. When closed, S1 forces just one output contact to close. The contact that closes will alternate between 11-14 and 21-24 on each successive S1 closure - ensuring even wear across both motors. • If closed, S2 forces both output contacts to close (irrespective of S1). However, to limit high current surges, both motors cannot start within T seconds of each other.
(M2) Output 2 (21-24) only • Supply permanently applied to A1-A2. • Closure of either S1 or S2 will close output contact 2 (21-24). Use when load 1 (11-14) is out of service.
(M1) Output 1 (11-14) only • Supply permanently applied to A1-A2. • Closure of either S1 or S2 will close output contact 1 (11-14). Use when load 2 (21-24) is out of service.
